Clinical Info

For the assessment of vitamin K deficiency. Vitamin K deficiency may be induced by obstructive
liver disease, obstructive icterus, malabsorption due to celiac disease, pancreatitis, diarrhea,
and antibiotic abuse; may be used to treat blood clotting disorders, bone metabolism disorders,
and hemorrhagic disorders of newborns.
Limitations
Overnight (12-hour) patient fasting is required. Consumption of supplements or
food with Vitamin K may elevate plasma concentrations of Vitamin K1 for testing.
Although lipemia does not interfere with the analytical measurement of Vitamin K1
by this test, Vitamin K1 levels are correlated with lipoprotein concentrations. As such,
all lipemic samples should be rejected given Vitamin K1 levels are expected to be
elevated in lipemic specimens1,2 and prevent evaluation for Vitamin K1 insufficiency.
This test was developed and its performance characteristics determined by LabCorp
It has not been cleared or approved by the Food and Drug Administration.
